I'm uninformed on this and not ready to read up right now. Is this because of wagers or emotional connection. Ok, I'll guess wagering.
I wouldn't begin to align all chinese with one of our friends, but he was all of these - an immensely hard worker with endless hours, a fabulous cook, superstitious. When we visited his new place, and he insisted we stay at their house, he offered my husband a sip of the precious aphrodisiac potion, which he tried, to be polite. No luck, the beds were a blanket and sheet over planks and besides we were exhausted already). He loved gambling, and had won in life so far, last I knew.
That isn't a knock, but part of my guess.
